This introduction to quantum field theory (QFT) is written by a
physical chemist for physical chemists, chemical physicists, and
other non-physicists with knowledge of quantum theory but who want
to explore ways in which they might use the power of QFT in their
investigations. This book starts where many graduate courses in
quantum theory that are offered to chemistry students leave off and
first develops some of the necessary tools, such as Fock algebra,
which is applied to solving the quantum oscillator problem. Then it
is used to develop the theory of coherent states, time-dependent
perturbation theory, and the treatment of bosons and fermions. With
this background, the QFT of a perfect gas is derived and a
connection to thermodynamics is demonstrated. Application to
imperfect gases provides a new approach to modelling gas-liquid
phase transitions. The book concludes with photons and their
interaction with molecular ensembles, and brings us to full circle
by deriving the blackbody radiation law, which started it all. The
power of the QFT methodology and the breadth of its applications
should fascinate the reader as it has the author.
